My fry just started free swimming this morning, but my BBS are not ready yet. I ran to my local fish store and the owner sold me powder he uses with his angel fry. He called it APR or something like that. He said to mix a little with water and use an eye dropper to squirt it into the tank. I can't tell if the fry are eating it or if I am doing it right. Anyone have any tips or have you even heard of this powder?

Wow cool! My angelfish laid their first batch of eggs but they got eaten by my rummynose tetras as soon as they became wigglers. Little rascals! I bought this food by Hakari called "Little Bites". It's a powder and sounds similar to the stuff you bought. I would just add a little at a time and see if it starts diappearing then add a little more. If it disappears as you're adding it, I would assume it's in the fry's belly
